JOSEPH P()ZNANSKI, OFNE\V YORK, N. Y., ASSIGNOR OF ONE-HALF TO HENRY M.HAAR, OF SAME PLACE.

VENT F 0 R CA s K s SPECIFICATION forming part of Letters Patent No.289,555, dated December 4, 1883.

' Application filed September 13, 1883. (No model.)

To all whom it may concern Be it known that I, Josnrnloznnnsn1, of thecity and county of New York, in the State of New York, have invented anew and useful Improvement in Vents for Casks, of which the following isa specification.

I11 order to operate successfully the valve of a beer-vent, while itmust be free to open for the admission of air when necessary in drawingthe beer from the cask, it must close absolutely tight, when the drawingceases, else all the gas in a keg will escape after the vent is drivenin, and the valve must close thus tightly even when the keg to which thevent is applied is tilted as kegs usually are when drawing beer fromthem.

The invention consists in novel features of construction andcombinations ofparts, hereinafter particularly described, and pointedout in the claims, whereby the desired ends are attained.

In the accompanying drawings, Figure 1 is -a vertical section of myimproved vent, and a portion of a cask-stave, wherein it is secured.Fig. 2 is a side view of the vent, also including a portion ofthe*stave; and Fig. 3 is an inverted plan of the vent, the valve-box andvalve being removed.

Similar letters of reference designate corresponding parts in the threefigures.

A designates the stave, and B designates the vent-plug or body of thevent inserted therein. It consists of a piece of cast-iron or othermaterial having a laterally-extending branch or arm, B, the outer end ofwhich turns downward, and has screwed upon it a valve-box, G, apacking-ring, a, of rubber or other material being used between thevalvebox and the part on which it screws to form a tight joint. tralaperture, b, and a valve-seat, c, surrounding the same on the inner andupper side of the said box.

D designates the valve of the vent, here shown as consisting ofa flatdisk seating on the seat 0. ,'ihe valve is provided with a stem, D,which extends downward through the aperture b considerably beyond thevalve-box C, and on the projecting portion of this stem The valve-box Ohas a cen-,

is a nut or collar, d, larger in size than the aperture 1). Theprojecting portion of the stem D may, if desired, be protected by aguard, E, attached to the valve-box O, as shown in Fig. 1.

When the beer-vents are in use they are commonly inclined from theperpendicular as the kegs or barrels to which they are applied aretilted, and it will be seen that air will be admitted through theaperture b if the valve D is simply canted or raised at one side off 60its seat without the valve being bodily lifted.

As to cantthe valve will require less suction within the keg or caskthan to lift it bodily, it will be seen that the valve will be verysensitive to any diminution of pressure in the keg or cask. In case thevalve-seat 0 should become clogged with saccharine or other solidmatter, so as to prevent the valve D from closing tightly, the valve maybe turned by grasping its stem on the nut or collar d with the fingers,and a new seat formed on the saccharine or solid matter. By providingthe stem D with a nut or collar, (2, larger than the aperture 1) thevalve is prevented from being lost when the valve-box O is taken off forcleaning or for any other purpose. In order that the valve D shall notclose the end of the branch or arm B, when raised against it, Ipreferably form in the end of the branch or arm a groove, 6, (best shownin Fig. 3,) which affords a clear passage for air, even if the valve bepressed up tightly against the end of said branch or arm.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination, with a vent-plug having a laterally-extending branchor arm, of a valve-box containing a valve-seat, applied to the end ofsaid branch or arm, a valve fitted to said seat, and having a stemprojecting downward through and beyond the valve-box, so that it may betaken hold of for the purpose of manipulating the valve, and a guardattached to the valve-box, and protecting the projecting stem portion,substantially as herein described.

2. The combination, with the vent-plug B formed with the aperture 1) andvalve-seat o, and the disk-valve D, having the stem D projecting throughand beyond the aperture 2), and there provided with a nut or collarlarger 5 than said aperture to confine the valve to the box,substantially as herein described.

3. The combination, with the vent-plug B and its branch or B, having inthe end the groove 6, of the valve-box (l, screwed upon 10 the exteriorof the said branch or arm, and

constructed with the apertures 22 and valveseat 0, and the valve D,working between said seat and the grooved end of the branch or arm B,and having a stem, D, projecting through the aperture 1), allsubstantially as herein described.
